334 Mr.-H. W. Bates on the Nymphaline 
of South Brazil. I obtained two specimens only, and these differ in 
the colour of the broad belt of the fore wing; in one example this 
is white, and in the other tawny orange. They both agree in the 
markings of the under side, and these leave no doubt as to their 
belonging to this species. The characteristic marks crossing the cell 
of the fore wing are sure guides in the determination, A. Agathina, 
in both sexes, having the cell of a reddish hue, crossed by four black 
stripes, the last lying a little beyond its termination. The males are 
common on the Upper Amazons, but the females are extremely rare. 
139. Apatura Selina, n. sp. 
3. Expanse 2” 4". Fore-wing apex moderately produced and broadly 
truncate, outer margin moderately incurved and dentate; hind wing with 
the outer margin scarcely rounded, dentate, produced into a dentiform 
lobe at the first median branch. Wings, above, dark brown, crossed by a 
discoidal common white belt, which on the fore wing passes a little beyond 
the median nervure ; nearer the apex of the fore wing lies a tawny-orange 
spot, distant from the white belt and touching the costa, and sinuate on 
its outer edge; outer limb of the wings traversed by two black lines; at 
the anal angle of the hind wing is a reddish spot, and, near it, the submar- 
ginal black line is bordered with grey: cell of fore wing crossed by two 
black lines. Costa of fore wing, near the apex, narrowly edged with 
whitish. Beneath, the fore wing is pallid, with similar marks to those 
above, and in addition there is an oblique, waved, black streak crossing 
the wing beyond the cell; the white belt is edged outwardly with dusky. 
The hind wing is silvery, with the white belt opake. 
Q. Expanse 2” 8”. Same as the male, except that the white belt 
is broader and, on the fore wing, tawny-orange, except near the hind 
margin. 
This species resembles A. Laura of Drury (Ill. 1. pl. 17. f.5, 6); 
but it is destitute of blue gloss above, and the apex of the fore wing 
is much less produced and more broadly truncate. It is more nearly 
allied to A. Linda of Felder (Faun. Lep. R. Negro, Sup. no. 119); but 
in the male of this species the discoidal belt of the fore wing is tawny- 
orange, and continuous with the subapical spot of the same hue. It 
may prove that we have here to deal with a species subject to great 
local modification, especially with regard to the colour and extent 
of the discoidal belt of the fore wing. I have a male example from 
South Brazil (30° S. lat.) which agrees with Amazonian specimens, 
except that it has this belt fulvous-coloured on the fore wing, but 
not continuous with the subapical spot as in A. Linda. A. Selina 
was a common insect on the Upper Amazons, and all the specimens 
I have examined are conformable to the description given above.
